feat: allow to view the verification key by providing the program name

[leruaa]

Motivation

Now that the ELF is not in the elf folder it harder to specify the path.

Solution

Adding a --program arg that just need the crate name.

Bonus: If there are multiple targets in the program, they will all be printed.
